This paper proposes a derivation of discrete-time queuing network analytical model based on dynamic random early drop (DRED) algorithm to manage and control congestion in early stages before it occurs, which is referred to as the 3QN model. The proposed model consists of three interconnected queue processing nodes. Expressions were derived to calculate performance measures, namely; throughput, and...
The Consultative Committee for Space Data Systems (CCSDS) File Delivery Protocol (CFDP) is a new international standard developed by the space agencypsilas to meet the growing space communication need for effective transfer of information in a wide variety of mission configurations of inter-planetary space links. The performance of CFDP in the deferred NAK mode has been evaluated in a theoretical...
Datasets of tens of gigabytes are becoming common in computational and experimental science. Providing remote visualization of these large datasets with adequate levels of quality and interactivity is an extremely challenging task, particularly for scientists who collaborate in widely distributed locations and their primary access to visualization resources is a desktop computer. This paper describes...
